No. 7. Assessing soiling worldwide

This summer has been quite fruitful. We have a perspective published in Joule, a multidisciplinary Cell Press journal, where we assess the global impact of soiling and we review the potential and challenges of various soiling mitigation techniques. The work was led by Klemens Ilse, at Fraunhofer CSP, and is available at: We should be provided with a 50 days' free access link soon. Make sure to check our Twitter feed (@NoSoilPV) not to miss it!

I also want to suggest the comment of Russ Jones, from KAKARE:

In addition, a new article is being published on IEEE JPV, titled: "Extracting and Generating PV Soiling Profiles for Analysis, Forecasting and Cleaning Optimization". It was accepted in September, and should be published online soon. Here, we introduce a monthly metric to characterize soiling, and we analyze the potential of using weather generation algorithms for the prediction of future soiling losses.

In September, I attended the 36th European Photovoltaic Solar Energy Conference and Exhibition, in Marseille, France: a great occasion to present our updates and to get some feedbacks on our work. Hopefully, some collaborations will also take off thanks to this event.

In less than a couple of weeks the International Soiling Workshop will take place in Marrakech, Morocco. This is an important event for the soiling community, with several experts from industry and academia worldwide. Registrations are still welcomed at:

On September 27th, I organized a stand for the European Researchers' Night, thanks to the support of the University and of two PhD students. We were part of the 60+ activities organized, and attended by more than 8000 people. We had fun with kids and families, showing how the solar energy works. We also had a working DUSST prototype there.

As tradition, the last paragraph of each post is about the beauty of Spain. Although, I am going to bend a bit this rule, with a first picture from Gibraltar, a small British peninsula. Fig. 1 was taken while walking on the Rock, a famous promontory populated by about 300 monkeys.

Let's get back to the Spanish border... thanks the warm weather, I could enjoy some time at the beach also in this first part of the fall. In Fig. 2, the dunes of Cabopino, near Marbella. Last, a picture (Fig. 3) from Cabo de Gata, a spectacular coastal area in Almeria. Strongly recommended.
